为验证不同浓度的金利康叶面肥在甘薯上的增产效果,用三种不同浓度的金利康水溶性叶面肥在甘薯生长的不同时期进行喷施,结果喷施后叶片表现为浓绿、叶厚、叶大、种蔓健壮、分枝较多,控上促下,调节营养生长和生殖生长,促进营养物质向薯块方向输送,结薯多、薯块大,达到了增产、增收和改善品质的效果。三种浓度均较空白产量显著增加,其中以金利康1 000倍液增产幅度最大,效果最好,宜推广应用。
To verify the effects of different concentrations of Jinli Kang foliar fertilizers on the sweet potato yield, three different concentrations of water soluble foliar spray were applied at different stages of sweet potato growth. Results showed that the leaves showed dark green color after spraying, Leaf thick, leaf large, strong seed vine, more branches, control on the promotion, the regulation of vegetative and reproductive growth, and promote the delivery of nutrients to the direction of tubers, tuber more, large tuber, reached a yield, income and Improve the quality of results. Three concentrations were significantly higher than the blank yield, which Jinlikang 1 000 times the largest yield increase, the best, should be widely applied.
